Application filed February 23, 1889. Serial No. 300,963. (No model.)Patented in England September 9, 1887, No. 12,245; in France November 3,1887. No. 186,756, and in Belgium November 4:, 1887,11'0. 79,415-

A springis provided which normally rock to and fro in the direction in which theholds the axis or peg when at rest in a verticarriage travels. A spring,(see Fig. 4: one

end of which is secured to the axis F and the' other end to the pin E,tends to hold the axis when at rest in a vertical or nearly verticalposition. Upon the axis is mounted the typedisk H, composed of two thinsheets of metal, one of the sheets being beveled at H. The object ofhaving the disk beveled at its-outer edge is to enable such inclinededge to become parallel with the paper receiving the impression, thesaid disk having secured between the plates a ring of india-rubber, onwhich isformed the type J, each letter or figure projecting for somedistance through a space in the serrated or notched periphery,

the notches corresponding in nu mber with the number of letters andfigures of the type, such notches being employed to insure that suchletters and figures follow one another in a straight line, the verticalguide-pin G on a part of the base-blate of the carriage entering a notchas the operator selects his letters and inclines the disk, so that thetype impresses the paper.

A central pin or peg F, projecting upward, has mounted thereon thetype-disk H, to which is secured a handle K, for the purpose of theoperator turning the disk around and enabling him to tilt it sidewise,which takes place every time a letter is impressed upon the paper. Asquare or other form of hole is shown at M in dotted lines in plan view,which hole is made through the carriage base-plate and is for thepurpose of allowing one of the type-letters to pass through when markinga letter upon the paper, by which means it is impossible to mark morethan one letter at a time.

An inking-roller for supplying ink to the type is shown at N, whichworks on a horizontal pivot P, secured to a light bracket attached to orforming part of the carriage, which pivot is by preference made ratherlonger than the depth of the said roller for the purpose of allowing theroller some motion in the direction of its axis, by which means the typeis more evenly inked.

In order to determine the distance between each letter or figure, I fixa ratchet-wheel R at one end of the roller B, and into thisratchet-wheel drops one end of a pawl or lever S, so that as thecarriage is caused to travel in the direction of the arrow the pawl Swill take into the teeth, and not only determine the distance betweenthe letters or figures printed, but prevent the carriage moving in thewrong direction.

In order to determine or fix the distance between one line of writingand another, I form a notch at X in the base-plate of the carriage, andwhen one line is completed the machine is removed to the left hand ofthe paper and placed in such a position that the line last written isvisible through the said notch, whereby equidistan ce between the lin esis accurately determined.

For the purpose of making the rollers sufficiently adhere to the paperto prevent slipping, one or both of the rollers B and C may be encircledwith india-rubber bands, as at V V.

The modus operandi is as follows: The operator after placing theapparatus on the paper, turns the type-disk H until the selected letteris opposite the guide-pin G, when the disk is tilted, causing theguide-pin to enter the corresponding notch and the selected letter toprotrude through the hole M in carriage base-plate, and thereby toimpress the letter on the paper. The disk is then elevated by theoperator and the rollerB pushed forward a distance represented by one ofthe teeth on the ratchet-wheel R in order to form the space between theletters, and on revolving the disk in selecting another letter the typeis brought into contact with the inking-roller N, thus constantly inkingthe type when the machine is'in use. In order to give the necessaryspace between each word, it is necessary to push the roller B forward adistance represented by two of the catches or teeth of the ratchet-wheelR and another letter selected and impressed as before described, themachine traveling bodily along the paper as the writing proceeds.

What I claim is 1. A type-writer consisting of a carriage mounted onrollers, a revolving disk having a serrated rim and provided with raisedtype on its lower side near the periphery and corresponding characterson the upper side, a handle to rotate the disk, a pivoted axis for thedisk to permit the disk to be rocked, a spring to return the axis to itsupright position, a guide-pin, and an inking-roller, the said carriagebeing provided with an opening to allow the type to pass through and anotch to aid in spacing between the lines, substantially as described.

2. A type-writer consisting of a carriage mounted on rollers, one of thesaid rollers having ratchet-teeth and the carriage having a pawltherefor, a revolving disk having a serrated rim and provided withraised type on its lower side near the periphery and correspondingcharacters on the upper side, a handle to rotate the disk, a pivotedaxis for the disk to permit the disk to be rocked, a spring to returnthe axis to its upright position, a guide-pin, and an inking-roller, thesaid carriage being provided with an opening to allow the type to passthrough and a notch to aid in spacing between the lines, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
